Young infants have repeatedly been shown to be slower than older infants to shift fixation from a midline stimulus to a peripheral stimulus. This is generally thought to reflect maturation of the neural substrates that mediate the disengagement of attention, but this developmental difference may also be attributable to young infants' slower…

Examines the potential contribution of different neural systems to developmental change in the duration of visual fixation, and the individual differences in that variable that are predictive of subsequent cognitive function. Presents hypotheses concerning two specific and independent neural systems and how they might contribute to individual and…
